To all whom it may concern Be it known that we, CHARLES L. Romans,

and WILLARD W. BROWN, citizens of the United States of MANLY C. Romans,

5 America, and residents, 7 respectively, of Rochester, Weehawken, and Feather River Inn, Blairsden, in the counties of Monroe, Hudson, and Plumas. States ofNew York, New Jersey, and California,hav e invented new and useful Improvements in Air-Distributing Means, of which the following is a specification. d

This invention relates to cooling and ventilating apparatus and more particularly 'to means useful in connection with such appa ratus whereby air delivered to the apartment to be ventilatedmay be distributed therein in a substantially uniform,manne'r.

In the application of Charles L. Rogers,

Manly C. Rogers and 'Willard W..1Brown,

, Serial No. 324,300, September 18, 1919, for

cooling and refrigerating apparatus, of

which the present application is a division,

there is disclosed an air, cooling and ventilat ing apparatus for buildings, such apparatus comprlslng means for Withdrawing air from the apartment or room tobe ventilated, causlng such airto pass in heattrans- 8 ferring relationship to a suitable cooling cooling, into the room or apartment. In introducing the cooled air into the place to be ventilated, it is desirable to admit such order. that full advantage may. be taken of the relatively highspecific gravity of such cooled air. in establishing a propericirculation of the cooled air throughout the apartment. It is manifestly undesirable, however, to permit such .airto enter as a solid and unbroken stream, assuch a stream of inflowing airwould undoubtedly cause openings distributedover the walls of the.

apartment is not feasible' from a practical medium andreintroducing such air, after air-at *a point substantially above the floor and preferably adjacent to the ceiling, in

through a single conduit, thatsomefeflicient distributing means be supplied, whereby-to secure a proper diffusion of the entering air,

As such distributing means must almost necessarily be arranged Within the apartment, it should notbe-of'unsightly appear-v ance nor produce an objectionable sound in its operatlon, and preferably the device .should beof suchcharacterthat no auxiliary power is required for its operation,

The object of the present invention is ac cordingly to provide an air delivery terminal of compact and pleasing appearance,

having no moving parts, and capable of in-- stallation at any desired .point in an apartment, and which at the same time is ca- Y pable of distributing air received through a single supply pipelin "all directions lat- .erally and in such manner as to; cause such air to"- be diffused in a substantially uniform manner throughout the apartmentand with- I out causing appreciable noise, or setting up undesirable drafts therein.

In; he accompanying drawings isillus trated by wayiof exampleone embodiment ofmeans suitable for carrying the invention into effect, and in such drawings FigQ l is a vertical, diametral cross section. illustrating the delivery terminal formvention and ing the subject matter of the present in- Fig. 2 is a diametral elevational view il- A lustrating an air coolin delivery. terminalv applied thereto.

0' system having such In Fig. 2 the numeral 1 cates thebasef ment floor, 2 the first floor, and 3 an upper" fioor of a building having. an air cooling and ventilating system; therein, suchfsystem comprising a cooling apparatus: 4 off, any

coolingapparatus being arranged within the basement and delivering the cooled air through a pipe 5 to a fan or pump device 6, From the fan or pump the air passes to I a reservoir 7, and from .such reservoir the known'type, but preferably "of the form disclosedin the application of Rogers, et al, .Serial-No. 324,300, filed September 18, 1919,

of which this application is a division, such stories of a building.- This riser pipe may preferabiy comprise the steam main for a steam heating system operating alternatively with the cooling system, and to which steam may be supplied from any suitable source by means of the pipe 11 controlled by the valve'12. 1

To the pipe 10 steam radiators such as 13, arranged within the variousapartments of the building, are connected by means of branch pipes 14, such radiators; being also connected to the down pipe 15 which at its lower end is connected to. the return steam pipe 16. The pipe 15 is also connectedto the pipe 18 which'leads to the air cooling apparatus 1, and for admitting air to such pipe from the various apartments of the building, intake devices 19 are provided. From' the pipe 10, branch pipes such as 20 i lead, such pipes preferably extending up wardly and along the ceiling of the apart- 'ments to be ventilated and having downwardly turnedextremities as 21 which project downwardly through the ceilings of the respective apartments. Upon the extremity of the down-turned end 21 of each pipe 20 is secured a substantially hemi-spherical' cup-like member 22 having a central hollow boss 22' which is internally screw threaded for engagementawith screw threads 23 upon the lower end of the pipe member 21.. The boss 22 is provided with openings 2 1 where by air issuing from the pipe 21 may pass laterally into the hollow of the cup 22 and thence upwardly'toward the ceiling. Resting uponithe boss 22 is a conical deflector device 25 concentric with the pipe member 21iand having an opening at its smaller I end for the passage of the latter, said deflector preferably hearing at its upper portion' as indicated at 26 against the ceiling and being retained in position upon thepipe by means of the cup 22. "The deflector 25 is of generally conical form, its sides however, flaring outwardly as illustrated in Fig. 1. While herein disclosed as an independent appliance, it is clear that the discharge orifice and associated parts may well be embodied in .a chandelier, or other ornamental or useful appurtenance within the apartment. 1

In'the operationof the apparatusthe air, after being cooled by passing through the cooling device 1 is forced by the fan or pump '6 into the reservoir Wand thence it passes up through pipes 8, 10 and 20 to the upper part of the apartment to be ventilated. The air then issues "through the downwardly directed end 21 of the pipe 20 and upon strikingthe inner curved surface of the cup 22 is deflected upwardly and against the outer surface of the deflector 25 whereby it iscaused to spread outwardly m" a broad sheet, covering a very substantial area of the apartment, and as it is delivered at the upper portion of the latter it natu' rally tends to fall by reason of its greater specific gravity. It will be noted that the air receiving devices 19 are located near the floor of the apartment so that the incoming air delivered through the terminal device illustrated in Fig. 1 tends to displace the warmer and foul air, causing the latter to pass outwardly through the devices 19 from which it may bereturned to the cooling device 4 for washing and cooling thus pro viding a'very thorough and complete circulation of air in the apartment. The delivery terminal as thus provided operates in a highly efficient manner to distribute air over the apartment and requires no mechanically driven parts for producing its proper function. The device is substantially noiseless in operation, occupies but little room and-may be. of decidedly ornamental appearance in accordance with the material from which it maybe made.

While as herein illustrated the deflector device 25 is shown as separate from the cup 22 it is evident that such elements might, if desired, be made as an integral structure, and it is also to be understood that various changes in the specific shape and arrange- .ment of the cup and deflector might Well be made without departing from'the spirit of the invention.

' What we claim and desire tosecure by Letters Patent of the United States is:

1. An air delivery terminal for ventilatingpurposes comprising an air supply conduit, a .cup like member having its open side presented opposite. to the delivery end.

of the pipe, and a deflector of: substantially conical fornr concentric with the pipe and having its smaller end. disposed substantially in, the plane of the edge. of the cup like member.

2.- An air delivery terminal for ventilating purposes comprising an air supply conduit, a cup like :member of substantially hemispherical form having its open side presented opposite to thedelivery end of the conduit, and a deflector of ,substantially conical form concentric with the conduit and having its smaller end disposed substantially in the" planeof the edge of the cup, the surface of the deflector flaring outwardly in a gradual curve.

3. An air delivery terminal comprisingan air supply pipe having a screw threaded extremity, a cup-like member having an axially disposed boss within its concavity, said boss being screw threaded for engagement like member carried by the pipe and having discharge openings formed therein, a cuplike member surrounding the sleeve and eX-' tending above the discharge openings there in to reversely deflect air in the direction of the feed pipe and an outwardly flaring defle'ctor member surrounding the pipe and having lateral portions curving outwardly and rearwardly from the cup to gradually intercept and deflect the air reversely deflected by the cup, said deflector terminating in an annular portion with a slight reverse curve to deflect downwardly from the ceiling the general upward current created along the deflector by initial direction 'of the air current thereagainst by the cup.
